Mechanical performance of narrow dental implants with varying lengths and angled abutments

Mechanical performance of narrow-diameter dental implants with varying lengths and abutment angulations remains a critical factor in long-term clinical success. Therefore, it is of interest to evaluate Quickdent implant systems under static and fatigue loading according to ISO 14801:2016E. Group 1 (3.5 mm x 10 mm, 25° abutment) and Group 2 (3.5 mm x 25 mm, 45° abutment) were tested using fifteen assemblies per group. Group 1 showed 418 N static and 182 N fatigue resistance, while Group 2 showed 454 N static and 160 N fatigue resistance with distinct failure modes. Thus, we show that longer implants offer higher static strength, whereas shorter ones perform better under fatigue conditions.
